Extended Atlas of Low-resolution Spectra (LRS) from the Infrared Astronomical Satellite

This dataset contains an updated atlas of spectra from the Low-Resolution Spectrometer (LRS) on the Infrared Astronomical Satellite (IRAS), which took spectra from 7.67 to 22.73 um with a spectral resolving power of 20-60. The updated atlas includes 11,238 spectra, including 5,425 spectra published in the original LRS Atlas, 5,796 spectra published in three later papers, and 17 spectra previously available online but not published.
